This is my code,here i need to replace the object
[CoutReplace[indexPath.section] replaceObjectAtIndex:indexPath.row withObject:#"1"];
when i am using this code it is crashing.
Bellow is my crash report.
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSArrayI replaceObjectAtIndex:withObject:]: unrecognized selector sent to instance 0x600000e6fe40'
Here "CoutReplace" is NSMutableArray.

I'm trying to iterate through an NSArray and check if an objectAtIndex is equal to a string.
NSLog(#"%#", myArray) // 3 items. 1 of them is "a"
for (id object in myArray)
{
NSLog(#"What"); // 3 times
if ([object isEqual:#"a"]) {
NSLog(#"Hello"); // Never gets executed
}
}
The problem is, the NSLog in the if statement never gets executed?

When I set it to isEqualToString, I get this error:
2015-03-30 14:42:54.206 MyApp[1575:50954] -[__NSArrayM isEqualToString:]: unrecognized selector sent to instance 0x7fe721ce3bf0

Your problem is that you have an array that contains three sub-arrays, each of which contain, what is presumably, a single string. You can tell this because of the extra ()'s around the strings in the log output, and by the fact that it's telling you that you tried to send a selector to __NSArrayM.
Here is a quick fix:
NSLog(#"%#", myArray) // 3 items. 1 of them is "a"
for (NSArray *array in myArray)
{
NSLog(#"What"); // 3 times
if ([array.firstObject isEqualToString:#"a"])
{
NSLog(#"Hello"); // Never gets executed
}
}
But as others have pointed out you probably want to use isEqualToString: since it will be more performant.
You may also want to reconsider the code that is generating this nested array structure, or the schema that you're using in general, because it seems... unnecessary. Without further information there's not much to be done.

The log exactly says NSString* po = getUser.ofUser; returns null or nil value.
You're passing this nil argument to the method [[QuoteMessageController SharedInstance] SendChatMessageTo: withContent: toUserId: andOFId:po andVerifyKey:];.
I have array like this:
(
{
code = "+39";
country = "Italy (+39)";
},
{
code = "+93";
country = "Afghanistan(+93)";
},
)
And i trying to get elements on loop like this discribed here
So there are my code:
int i = 0;
for (id key in self.codes) {
NSDictionary *value = [self.codes objectForKey:key];
if(row == i)
{
return [value objectForKey:#"country"];
}
i++;
}
and i have this error:

libc++abi.dylib: terminating with uncaught exception of type NSException
(lldb)
How i can to fix it? and Why i have error?
Whe i do debug i see that error in this line :
NSDictionary *value = [self.codes objectForKey:key];
It looks like self.codes is an array; you can't access that like a dictionary. The correct way to use your code is like this:
int i = 0;
for (NSDictionary *value in self.codes) {
if(row == i)
{
return [value objectForKey:#"country"];
}
i++;
}
However, it really just looks like you're trying to access this:
self.codes[row][#"country"]
The error is that you call a NSDictionary method on the NSArray method.
self.codes is a NSArray, it needs to be a NSDictionary.
I'm getting an exception while running iOS app in simulator
2013-09-16 18:03:44.346 DEV[26529:c07] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSDecimalNumber isEqualToString:]: unrecognized selector sent to instance 0xf98fc70'

UPD:
Exception is caused by the following code:
if([self.media.idtype isEqualToString:IMAGETYPE])
Where idtype is #property(retain, nonatomic) NSString *idtype; and IMAGETYPE is static NSString *VIDEOTYPE = #"2";
How can I see function names instead of addresses?
isEqualToString can compare two NSstrings not the other type of data that u are comparing which is NSDecimalNumber
convert your NSDecimalNumber to nsstring then do this
NSDecimalNumber* dec1;
NSString* str;
str = dec1.stringValue;
NSString *str2=#"world";
[str isEqualToString:str2];
There is some where in your code you are setting the value of property idtype (self.media.idtype). This must be the source of the problem:
Possible Problems could be Extracting contents from Webservice and while parsing you might be assigning it to the self.media.idtype object.
I'm searching an NSString with an email to find the # character. Here's the code:
NSRange range = [string rangeOfString:#"#"];
if (range.location != NSNotFound) // do stuff
Here's the error I'm getting...
-[__NSCFNumber rangeOfString:]: unrecognized selector sent to instance 0x1e51c550
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFNumber rangeOfString:]: unrecognized selector sent to instance 0x1e51c550'
Your string variable points to an instance of NSNumber, not an instance of NSString. You are initializing it incorrectly.
